Fit people are commonly deemed as healthier and sexier than those who have a few extra pounds. But some people remain slim, no matter what. According to a recent study, these folks have “skinny genes” which help them keep fit without much effort.
The research, published in the PLOS Genetics journal and headed by a University of Cambridge professor, revealed that being slim is dependant on genetics. Accordingly, thin people who can remain fit no matter what they eat or do, have to thank their DNA for that. The study revealed that so-called “skinny genes” are what helps some people be slim.
“This research shows for the first time that healthy thin people are generally thin because they have a lower burden of genes that increase a person’s chances of being overweight and not because they are morally superior, as some people like to suggest,” said Professor Sadaaf Farooqi from the University of Cambridge.
“Skinny Genes” Help Some People Remain Slim
“It’s easy to rush to judgment and criticise people for their weight but science shows that things are far more complex. We have far less control over our weight than we might wish to think,” the researcher added.
To reach that conclusion, the scientists analyzed 1,600 healthy, very slim people with a BMI lower than 18, commonly considered underweight by experts. These participants were compared to 2,000 obese and more than 10,000 normal weight people. The very thin group presented fewer genes linked to obesity and an increased number of genes connected to thinness. The scientists called them “skinny genes.”
Since obesity is an increasing problem, nowadays, every discovery like the one presented above is more than welcome. However, even though the scientists revealed that slim people have “skinny genes,” it’s nothing the experts can do, for the moment, for obese people. That, at least until gene editing would be available in humans.
